Check Existing Rows Batch Numbers

Before you initiate an export process, you should verify that rows do not contain an if_row_batch_num matching the batch number you plan to use. If such rows do exist, you should either make sure that they do not contain data you need to preserve, or change the batch number for the export process. In each row that you are exporting, you may also want to set the IF_ROW_STAT column to FOR_EXPORT.
